speed is not ideal #1384

Closed logernLee closed 3 years ago

logernLee commented 3 years ago

I run this program on the mt7688(cpu:480MHz, RAM:ddr2 256M, flash:32M) board and compile the version of mini.During the test, I found that the overlay is not ideal, and even the speed of two network cards is not as fast as that of one network card. How can I solve these problems? Do you have any good suggestions.thank you.

Ysurac commented 3 years ago

The card is really slow. You can disable encryption but even with that this will never work well.

logernLee commented 3 years ago

How to disable encryption? And my print log always appears as follow: Mon Nov 16 14:08:06 2020 daemon.warn odhcpd[3504]: A default route is present but there is no public prefix on lan thus we don't announce a default route! Mon Nov 16 14:08:06 2020 daemon.err odhcpd[3504]: Failed to send to ff02::1%lan@eth0 (Permission denied)

Is it working properly?

Ysurac commented 3 years ago

In System->OpenMPTCProuter, "Advanced settings" checkbox

This is related to IPv6, this will be fixed in next release but this doesn't impact anything.

logernLee commented 3 years ago

Thank you for your reply.

logernLee commented 3 years ago

error there is something wrong in my web. I can connect to VPN and proxy server with two 4G cards, but I can't connect to proxy server with three cards. What is the cause of this? Could you tell me what happened?thank you.

Ysurac commented 3 years ago

Check log in State->System log.

Adorfer commented 3 years ago

What speed would you consider "ideal"? What is the speed you actually see currently "not ideal"?

logernLee commented 3 years ago

two 4G card should faster than one card

Adorfer commented 3 years ago

o.k, my misunderstanding! "card" does refer to USB-4G-modems!

what values do you get for 1 modem, 2 modem, 3 modem? especially on LTE, if a cell is overloaded or the modems are "only 20cm apart" we saw, that the total bandwith "hard ceiling" for all adapters together.

what does your mptcp-graph look like while doing tests? do you see balaninc between adapters grafik

logernLee commented 3 years ago

OK, I'll test it tomorrow. Thank you for your reply.

The first picture is that I don't use the server (Download peak : 9.43mb/s, Upload peak: 2.26mb/s).

The second is a picture using a card (Download peak : 5.05mb/s, Upload peak: 3.04mb/s),

The third is a picture using two cards (Download peak: 4.13mb/s, Upload peak: 4.35mb/s),

The fourth is a picture using three cards (Download peak: 3.06mb/s, Upload peak: 3.89mb/s).

eth0 is the network card that my device connects to the computer.

When I download, each card can also see traffic running.

Adorfer commented 3 years ago

sorry, you are looking into the wrong chart, please have look at the mptcp-stats, where you have "one color per WAN-interface".

Adorfer commented 3 years ago

So the traffic looks well balanced between the LTE-radios. if the total speed "with 3" is like "with only one": Get at least 1m distance between the radios to reduce interference locally, let them look out of different windows of the building or try to point to different cell to towers. best: different Sim card with providers of really different networks (not just resellers of the same operator)

logernLee commented 3 years ago

but I use only one card: 1

logernLee commented 3 years ago

Is it the server problem？

Adorfer commented 3 years ago

I assume it's the cell or the consumer grade quality of the modems. (as stated in my previous comment)

Ysurac commented 3 years ago

For aggregation a proxy (by default Shadowsocks) and a VPN (by default glorytun TCP) are used. They are encrypted. And with the CPU of this board it's really limited. You can disable encryption in System->OpenMPTCProuter, "wizard" tab and "advanced settings" checkbox. Check load average on the board during test, I think it's really high.

logernLee commented 3 years ago

thank you Ysurac, Now I'm testing with another board(CPU:ipq4019).

logernLee commented 3 years ago

I use 4G modules(EC20),Dial with QMI. Connect to the board via USB.I don't know how to debug it(the cell or the consumer grade quality of the modems),Do you have any good suggestions, @Adorfer. I've changed the cards of other operators, which seems to be useless.

Adorfer commented 3 years ago

what is the cpu load (graph) during the tests? grafik

logernLee commented 3 years ago

Is there a problem with the load? load

logernLee commented 3 years ago

cpuinfo

Adorfer commented 3 years ago

goal:

On a 4 core system: try to stay under load=2.

logernLee commented 3 years ago

OK,thanks for your reply.I tried to reduce the load.

Adorfer commented 3 years ago

?!? how? the load is caused by the traffic! You definitly need a faster system! (most of the load will be caused by SQM. using mobile data without SQM will decrease 'user experience' A LOT)

Ysurac commented 3 years ago

As I already said, possible to disable encryption, at least for testing.

logernLee commented 3 years ago

I've turned off encryption and SQM, but It's still the question.I'm trying other solutions.
